| alistipes onderdonkii sp. nov. and alistipes shahii sp. nov., of human origin. | two groups of previously unknown gram-negative, strictly anaerobic, pigment-producing, rod-shaped bacteria, which phenotypically and phylogenetically displayed a close association with the recently described species alistipes finegoldii, were characterized using phenotypic and molecular taxonomic methods. a 16s rrna gene sequence divergence of approximately 3 % between the two unknown bacteria and a. finegoldii, as well as distinguishable biochemical characteristics, demonstrates that these orga ... | 2006 | 16902041 |
| acetobacteroides hydrogenigenes gen. nov., sp. nov., an anaerobic hydrogen-producing bacterium in the family rikenellaceae isolated from a reed swamp. | a strictly anaerobic, mesophilic, carbohydrate-fermenting, hydrogen-producing bacterium, designated strain rl-c(t), was isolated from a reed swamp in china. cells were gram-stain-negative, catalase-negative, non-spore-forming, non-motile rods measuring 0.7-1.0 µm in width and 3.0-8.0 µm in length. the optimum temperature for growth of strain rl-c(t) was 37 °c (range 25-40 °c) and ph 7.0-7.5 (range ph 5.7-8.0). the strain could grow fermentatively on yeast extract, tryptone, arabinose, glucose, g ... | 2014 | 24899658 |
